Shi Shenchang is resetted at 30 DEG C or less.Preferably, it is further sleeved with the first thrust ball bearing B450 on the 5th cold wind axis B350,
The first thrust ball bearing B450 and cold wind helical gear B440 assembly fix, and the both ends memory spring B460 respectively with memory bullet
Spring B460, power plate B140 assembly are fixed.Preferably, it is further fixed on stop collar B351 on the 5th cold wind axis B350, it is described
Stop collar B351 is for limiting the maximum displacement that cold wind helical gear B440 is moved up in the 5th cold wind axis B350 axis.
The 5th cold wind axis B350 other end and keep disk B470 assembly fix, the cold wind helical gear B440 and it is interior tiltedly
Toothed portion B431 engaged transmission, the interior helical teeth part B431 are arranged on lower mounting cylinder B430, when original state, cold wind helical teeth
Wheel B440 is not contacted with interior helical teeth part B431, is engaged.It keeps being provided with several perforative air guide through slot B471 on disk B470, lead
Gas through slot B471 keeps disk B470 for moving air through.
The 5th cold wind axis B350 and holding disk B470 assembly are fixed, and the lower mounting cylinder B430 is also sleeved on supplemental cartridge
Outside B150, the supplemental cartridge B150 is fixed on lower supporting plate 120, and the end face supplemental cartridge B150 is contacted with disk B470 is kept, thus
It is supported to keeping disk B470 to be formed;The lower supporting plate 120 is also assembled with cold wind one end cylinder B110 and is fixed, the cold wind cylinder B110
Inside is separately installed with seal disc B123, lower seal disc B121, installs between the upper seal disc B123, lower seal disc B121
There is piston B122 and upper seal disc B123, lower seal disc B121 seal assembly with cold wind cylinder B110 respectively and fix;
On the cold wind cylinder B110, be provided with air intake duct B111 above upper seal disc B123, the upper seal disc B123 with
The corresponding position air intake duct B111 is equipped with refrigerator pipes B320, the first open end B321 of the refrigerator pipes B320 be located at piston B122 with
Between upper seal disc B123, the second open end B322 be located between piston B122 and lower seal disc B121, and upper seal disc B123,
Conduction oil is filled in cold wind cylinder B110 between lower seal disc B121.
Third cold wind one end axis B330 passes through piston B122 and assembles with piston B122 and fixes, the third cold wind axis at this end
B330 and the one end reset spring B310 are set with, and the reset spring B310 other end contacts or assemble fixation with lower seal disc B121;The
The three cold wind axis B330 other ends pass through upper seal disc B123, and this end can spherical rolling dress by ball lid B332 and ball B331
Match;The refrigerator pipes B320 and piston B122 is axially movable, seals assembly, and the piston B122 and cold wind cylinder B110 sealing fill
Match;
The cam surface B411 of the ball B331 and cam B410 is adjacent to, and it is another that the cam B410 is fixed on the 4th cold wind axis B340
One end, and the 4th cold wind axis B340 is equipped with the second impeller B420 on the part between lower supporting plate 120 and cam B410.
When temperature is higher in advertisement cabinet 310 and reaches memory spring elongation temperature, memory spring elongation, to drive cold
Wind helical gear B440 is moved down, until cold wind helical gear B440 and interior helical teeth part B431 is adjacent to, engaged transmission, due to advertisement cabinet
310 rotation, therefore interior helical teeth part B431 also can circular-rotation, to drive cold wind helical gear B440 along interior helical teeth part
B431 circumference does planetary rotation, this just drives the 4th cold wind axis B340 rotation, so that cam, the second impeller be driven to rotate synchronously
When the second wheel rotation, extraneous gas can be pumped to cold wind cylinder B110, be then sent to advertisement cabinet 310 by similar and fan
It is internal.And third cold wind axis B330 is intermittently axially overcome reset spring elastic force by cam surface B411 by it after cam rotation
It pushes down on, so that piston axial reciprocating under the pushing of third cold wind axis B330 and the reset force of reset spring is mobile.
This just forms piston motion, and when piston moves down, conduction oil enters refrigerator pipes B320 from the second open end B322, and first is open
Hold B321 by negative pressure, therefore conduction oil is in refrigerator pipes B320 internal circulation flow.When piston moves up, conduction oil is opened from first
It puts end B321 and enters refrigerator pipes B320, the second open end B322 is by negative pressure, therefore conduction oil is in refrigerator pipes B320 inner recirculation flow
It is dynamic.Freeze to realize to the air-flow for entering advertisement cabinet at this point, air-flow blows to refrigerator pipes B320 from air intake duct, with raising pair
The heat dissipation effect of advertisement cabinet.
Referring to Figure 18-Figure 19, it is preferable that piston two sides form larger pressure difference in order to prevent, are making to influence conduction oil
Flowing, can be respectively set two intercommunicating pore B1222, each intercommunicating pore B1222 is wherein set one end on piston B122 in cold pipe
It is equipped with seal groove B1221, the seal groove B1221 side wall is hinged by the one end articulated shaft B620 and check valve sheet B610, described
Check valve sheet B610 can seal assembly with seal groove B1221 and be connected to cut off intercommunicating pore B1222 flow piston two sides.
Two check valve sheet B610 are separately mounted on side face of piston ring, thus will when control piston is moved up or moved down respectively
The conduction oil of its two sides is connected to.Preferably, torsional spring is also equipped between the check valve sheet B610 and piston, the torsional spring is used for
Generation makes check valve sheet B610 to the torsion of seal groove B1221 rolling assembling.
When piston moves down, conduction oil initially enters refrigerator pipes, and when thermally conductive oil pressure is greater than torsional spring torsion, it is located at upper
The check valve sheet B610 rotating opening of side, to be connected to the conduction oil of two sides, can reduce so thermally conductive oil flow rate in refrigerator pipes,
Pressure prevents the conduction oil in refrigerator pipes from generating high temperature due to extruding.
When piston moves up, underlying check valve sheet B610 rotating opening, so that it is connected to the conduction oil of two sides, such energy
Thermally conductive oil flow rate, pressure in refrigerator pipes are enough reduced, prevents the conduction oil in refrigerator pipes from generating high temperature due to extruding.
This design can either guarantee to provide enough driving forces to the conduction oil in refrigerator pipes, and can be avoided refrigerator pipes
Interior thermally conductive oil flow rate is too fast, to influence to freeze, setting conduction oil oneself generates larger heat.
It is, of course, also possible to which electronic refrigerating sheet chill surface is to conduction oil refrigeration, heating surface in conduction oil built-in electronic cooling piece
Outside cold wind cylinder B110, so that electronic refrigerating sheet can freeze to conduction oil after being powered.Certainly, this is the prior art,
It is not described in more detail here.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
